S-94100A110 M3 Press-Fit Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh or humid industrial environments.
• Quick, secure installation via press-fitting into panels as thin as 1.53 mm, reducing assembly time and eliminating the need for additional locking hardware.
• Reliable thread engagement with Class 6H metric coarse thread (M3 x 0.5), providing consistent clamping force and vibration resistance in right-hand threaded applications.
• Optimized head design featuring a 5.56 mm OD round head and 1.5 mm height for a low-profile, flush finish that minimizes protrusion in compact assemblies.
• Precision fit and alignment using a standard No. 19 drill bit (0.166" diameter), ensuring accurate placement and reducing installation errors.
• Environmental compliance with RoHS 3 (2015/863/EU) standards, making it suitable for use in regulated electronics and consumer goods industries.
• Reduced component count by integrating nut functionality directly into sheet metal, lowering overall weight and simplifying BOM management.

Professional Applications & Engineering Value

This M3 press fit nut is engineered to solve common challenges in sheet metal assembly, where welded or clinched nuts can distort thin panels or require secondary operations. The 18-8 stainless steel material offers excellent corrosion resistance, making it ideal for electronics enclosures, automotive control modules, and outdoor equipment that face moisture or chemical exposure. Its round head press-fit design ensures a permanent, torque-resistant installation in panels as thin as 1.53 mm, eliminating loose hardware and maintaining thread integrity under vibration. With a coarse thread pitch and Class 6H thread fit, it provides rapid engagement with mating screws, speeding up production while delivering reliable performance in high-volume manufacturing environments.

Specification Summary & Compliance

This press-fit nut conforms to metric coarse thread standards (M3 x 0.5) with a Class 6H thread fit for consistent dimensional accuracy. It is designed for use with a No. 19 drill bit (0.166" diameter) and requires a minimum panel thickness of 1.53 mm. The product is manufactured in compliance with RoHS 3 (2015/863/EU), ensuring it is free of restricted hazardous substances for global market acceptance.
